Abstract:

[ANGLÈS] Automated Measuring Stations for river quality monitoring have been used to generate
on-line measurements of water quality variables. Even though a high degree of automation
has been implemented at the levels of measurements, maintenance and control, data
management and the resulting access to errors and uncertainties.
Besides managing a monitoring program, there is the responsibility to ensure high
quality data with data and methods that are broadly accessible, and as cost-e ective
as possible. Moreover, higher assurance is needed to analyse, interpret, and apply data
that are being collected so as to form monitoring networks that are designed to promote
comparability of data across sites and across scales of space and time.
monEAU (monitoring of water, "eau" in French) is the next generation of water quality
monitoring networks. This project has as vision to provide some tools to get a
exible
and open modular system, a high quality/performance database, remote use, automatic
data quality assessment, user-friendly and user-oriented software, and proactive and
exible
maintenance.
In the context of the project, the objective of this thesis was to e ciently monitor,
collect and manipulate water quality data such that unreliable data due to anomalies
in sensors, insu cient maintenance tasks, severe environmental conditions and other
external factors can be minimized. To achieve these goals it was required to maintain
and keep the monitoring stations working, collect the data, analyse samples in the laboratory
to verify sensor data, create an appropriate database, import all collected data
to a database, and nally export the data to statistics software and data manipulation
programs for posterior analysis.
